Abstract
A lidar sensor system and method use the parallax phenomenon to determine one or more attributes of an object, such its distance, size, or shape. An optical element illuminates the object with a linear beam along a first plane. A photodetector is displaced from the optical element so that it detects the reflection of the linear beam from the object along a second plane, which is at an angle to the first plane. A computer-implemented line detection module determines a measure of deviation of the linear beam reflection from a vanishing point of the first plane. A computer-implemented analysis module determines the attribute based on the measure of deviation.
